Product Summary

The hard alloy ring is made from hard alloy. Sealing rings, such as O-ring seals, are generally known. These universal sealing rings can be used for statically or dynamically sealing machine elements. They have the advantage of being suited for a wide variety of possible applications, and of being simple and cost-effective to manufacture.

A sealing ring comprising at least eight sealing edges, wherein at least two sealing edges are disposed on a radially inner surface of the sealing ring and at least two sealing edges are disposed on a radially outer surface of the sealing ring, wherein a concave transition region is disposed between each of two radially inner sealing edges and two radially outer sealing edges, wherein the respective concave transition regions which are between the radially inner sealing edges and radially outer sealing edges. And they are intersected by the same radial plane, having different radial depths, and wherein the eight sealing edges include centrally disposed radial sealing edges and further sealing edges, all of the further sealing edges except the centrally disposed radial sealing edges have a conforming design.
